To wonder how to get rid of liquid fat?

We keep being told not to pour oil or liquid fat down the sink because it causes problems for the water companies.

How are we meant to dispose of it? Googling says we should put it into a glass or plastic container and throw it into the main waste but we are supposed to recycle those things aren't we?

I don't have suitable empty glass or plastic containers just lying around and I certainly don't have plastic containers with lids apart from the ones I want to keep like Tupperware.

What do most people do with it?

Animal Fat that goes solid when cold: pour in a small bowl, scrape out onto cardboard and dispose in bin

Fat that stays liquid: YES we do keep a small spare plastic bottle, decant into this, then take to tip when full

Teawithfrenchtoast · 13/07/2026 16:25

we have a glass jar under the sink and pour whatever liquid fat we have into that then bin it when it’s full.

Bunny65 · 13/07/2026 15:58

If it’s not a large amount just pour it straight into the bin.

QuietComet · 13/07/2026 15:12

Pour into a mug and then, when solid, scrape into a bin.

I don't have much but pour it into an empty yoghurt pot, wiping what's left into the pot with kitchen towel, then scrunch the kitchen towel into the pot and bin it.
One small yoghurt pot isn't going to make much difference compared with the damage that's done by pouring it down the drain.
If I roast something like a chicken, I line the pan with foil first. Let the fat congeal and fold the foil round it before binning

I’m a peasant and when the cooking tray for the chicken is empty and cooked down I pour all the fat, jelly bits and meat scrapings into a remakin or similar. Out in fridge overnight so top solidifies - scrape that off and put in an airtight pot in fridge for week or so and use as chicken dripping. Yum. I then either use the leftover jellyfied part as a stock pot when in next cooking and need chicken stock or freeze until I do.

If making a chicken risotto and I don’t have proper chicken stock then the dripping part is amazing in lieu of oil for frying onions etc and the stock pot part I dissolve in hot water and ladle in. Tastes amazing

we have a deep fat fryer and when we clean the oil out we put the liquid into the old bottle and leave it out with the food waste bin. Any small amounts of liquid fat goes into the bag in the food waste bin.

If you use kitchen paper/paper towel in the kitchen, keep the used pieces and pour the oil over these.
I often have several dirty scrunch up paper towel in the bin, so once any oil/fats have cooled I pour it slowly over these in the bin.

If you have a baby in the house, I often pour oil/fats into a used nappy (obviously just a wet one that wasn’t full).

Piknik · 13/07/2026 13:49

Pour into small bowl, let solidify, bin.

pour into container, bin.

pour into foil, scrunch close, bin.

pour into freezer bag, bin.

poir into freezer bag, freeze to solidify if it’s runny fat, bin.

how is this hard?

FizzingAda · 13/07/2026 13:42

I put a couple of sheets of kitchen roll into the fat or oil to soak it up, when cool put the sheets in a plastic bag (the sort of thin bag you for supermarket veggies), knot and put in the general waste bin.

Makingsenseofitall · 13/07/2026 13:33

I just collect it in an old jam jar and bin the jar when it is full

hallouminatus · 13/07/2026 13:28

On the compost heap.

Greengage1983 · 13/07/2026 13:15

If its only a few tablespoons, I just leave it to cool then tip it straight in the bin.

CasperGutman · 13/07/2026 11:43

We collect waste fat in a plastic pot with a well-fitting watertight lid - some brands of houmous use good ones. It takes a good while to fill. Then we wrap the pot in an old plastic bread bag as double containment, and hopefully to help prevent the lid being dislodged. This goes in the general waste bin, which in our area is incinerated in an energy-from-waste plant. I'd imagine it releases plenty of energy when it goes up.

The waste here will be a mix of solid and liquid and room temperature. Yes, we could possibly cool the fats that will solidify and dispose of them separately, but at this time of year they'd surely melt again in the wheelie bin or food waste caddy sitting out in the sun, making a horrible mess.

A downside of this is that one plastic pot and one soft plastic bag are not recycled, but I think this is a lesser evil than blocking the sewers with fat.

My DH pours the fat from our burgers in the air fryer into an old empty yoghurt pot, lets it solidify then throws it in the bin. Easy as pie 😁

If it’s a liquid that will solidify when cold I wait till it’s cold then wrap and bin it. If it’s oil that won’t I pour in an empty bottle and bin it.
You can’t possibly put everything in to exactly the right bin so I don’t over think it

I do this - chill it so it's a solid lump then you can just chuck it in the bin.
People putting oils and fats down drains is why there are vast 'fatbergs'.

Chocolateistheanswer2026 · 13/07/2026 11:03

I either use an old jar with a lid or pour into a can and stuff some paper towel in to soak the oil up.

WonderingAndOverthinking · 13/07/2026 10:23

Line a bowl with kitchen roll, tip it in and leave until solid. Chuck in bin/food waste.

if it’s not going to solidify, mix it with flour until there’s no liquid left.

No need to buy specialised products.

InQuiresandplaceswheretheysing · 13/07/2026 10:20

I put it in an old glass jar and throw it way when full

Oioiqueen · 13/07/2026 10:12

I let it solidify and then use kitchen towel to wipe it out of the dish and then bin it.

You could use a gravy separator for the pork juice & fat. Chill it in the fridge till it separates, pour the juice down the sink and scrape the fat into the food bin.

Why would you need another plastic accessory in the kitchen? Just cool meat juices pour into a beaker and store in the fridge.
Fat on top sets solid and seals in the meat juice.
Store like that and use for gravy or stirfrys.

Solid fat can be wrapped in old paper and thrown into waste or made into bird fat balls if not salty.

MyGirlJ · 13/07/2026 10:01

I don't use a lot of liquid fat as I never deep fry, but sometimes have some to dispose of from shallow frying things like fried eggs. I always keep a bag of cheap porridge oats in the cupboard. Aldi own brand are less that £1. I sprinkle these into the frying pan and leave it a few hours to absorb all the oil. I then scrape the oily oats into my food waste bin. This is the best method I've found.

Beachbeach · 13/07/2026 10:01

If it’s solid ish I wipe it up with kitchen roll and bin in. Sometimes I pour it straight in our bin bag and lets it go into whatever is in the bin already

askmenow · 13/07/2026 09:55

For liquid oils, I wait til it cools and scrunch up some newspaper into the bin then pour the oil on top so it absorbs.

With pork or solid setting fats, cool and scrape into folded newspaper and discard into waste bin.

Bin is good for three days.

Ohthatsabitshit · 13/07/2026 09:35

If it’s vegetable oil and liquid just strain it and reuse it. You can get a metal jug with a strainer on the top. If it’s meat fat and gloopy, just put it in the food recycling box on top of the food.

Sooverwork · 13/07/2026 09:31

In warmer weather I just dig a small hole in the garden and pour it in there . Other times I’ll just place it in a disused glass or plastic tub and throw it in the landfill bin .
